52 System Architecture System Architecture This section describes the processor s configuration on the EZ-KIT Lite board. Figure -. System Architecture The EZ-KIT Lite has been designed to provide access to all the capabilities of the ADSP-9 processor. The EZ-KIT Lite board can be configured to boot in all of the possible ADSP-9 boot modes. For information about configuring the boot mode, see Boot Mode Select Switch (JP6) on page ADSP-9 EZ-KIT Lite Evaluation System Manual

53 EZ-KIT Lite Hardware Reference The processor core voltage is.5v, and the external interface operates at.v. The input clock to the DSP is a 6-MHz through-hole oscillator. Footprints are provided on the board for a surface-mount oscillator or a through-hole crystal. The speed at which the core operates is determined by the configuration of the multiplication factor switch (SW4) at reset and the state of the BYPASS jumper (JP7). (See Bypass Mode Select Switch (JP7) on page -9 and DSP Clock Multiplier Select Switch (SW4) on page -0.) By default, the processor core runs at 60 MHz. External Memory Interface (EMI) The External Memory Interface (EMI) is connected to a 5K x 8-bit Flash memory. This memory is connected to the boot memory select (~BMS) pin and the memory select 0 (~MS0) pin, allowing the Flash memory to be used to boot the processor as well as store information during normal operation. Refer to Memory Map on page - for information about the location of the Flash memory in the processor s memory map. All of the address, data, and control signals are available externally via two off-board connectors. The pinout of the EMI connectors (P0, P) is shown in Schematics on page B-. The upper 8-bits of the data bus (D5 D8) can also be used as programmable flag pins. Host Port Interface (HPI) The Host Port Interface (HPI) signals are brought to an unpopulated off board connector P. This allows the HPI to interface to a user application. The pinout of the host port connector (P) is shown in Schematics on page B-. ADSP-9 EZ-KIT Lite Evaluation System Manual -

54 System Architecture SPORT0 Audio Interface SPORT0 is connected to the AD885 SoundMAX codec (U0). Two.5mm stereo jacks (P, P4) allow audio to be input and output. You can supply an audio input to the Codec Microphone Input Channel (MIC) or to the stereo LINE_IN input channel. The jumper settings of JP determine the codec channel driven by the input jack (P). The PF6 programmable flag, which is connected to the reset pin of the AD885 codec, allows the processor to reset the codec. SPORT0 is also routed to an off-board connector (P6). When you use the off-board connector, the codec must be disabled to avoid bus contention. JP disables the codec by putting it into reset and disabling the codec outputs from driving the processor s SPORT inputs. For more information about disabling the codec, see Telephony Codec Disable (JP) on page -8. SPORT Telephony Interface SPORT is connected to the AD80 telephony codec (U). The telephony interface provided by the AD80 allows the processor to act as a modem on a standard telephone line. Four of the general-purpose pins of the AD80 codec are used. The following table gives the function of each of the general-purpose pins. Table -. AD80 General-Purpose Pin Function AD80 Pin G[0] G[] G[4] G[5] Description Used to connect or disconnect from the telephone line Detects when the phone is ringing Used as a speaker output, to monitor the telephone communication Connected to an LED.
